Which versions of Keygraph Shannon are affected by CVE-2026-29023?

Keygraph Shannon routers containing hard-coded API credentials expose organizations to unauthorized authentication and potential system compromise if the router component is enabled and…

How to fix or mitigate CVE-2026-29023?

Within 24 hours: Audit all Keygraph Shannon deployments to identify if router components are enabled and exposed to untrusted networks; immediately restrict network access to affected routers via firewall rules. Within 7 days: Implement network segmentation to isolate router components to trusted administrative networks only; document all affected systems and their exposure status. Within 30 days: Contact Keygraph for patch availability and timeline; evaluate alternative solutions or plan phased replacement if patches remain unavailable; complete remediation of all internet-facing instances.

DescriptionCVE.org

Keygraph Shannon contains a hard-coded API key in its router configuration that, when the router component is enabled and exposed, allows network attackers to authenticate using the publicly known static key. An attacker able to reach the router port can proxy requests through the Shannon instance using the victim’s configured upstream provider API credentials, resulting in unauthorized API usage and potential disclosure of proxied request and response data. This vulnerability's general exploitability has been mitigated with the introduction of commit 023cc95.

AnalysisAI

Keygraph Shannon's router component exposes a hard-coded API key that allows unauthenticated network attackers to intercept and proxy requests through the application when the router is enabled and accessible. Attackers can leverage this static credential to abuse upstream provider API resources and potentially access sensitive request/response data belonging to legitimate users. No patch is currently available for this vulnerability.
